AD7383-4 Part Attribute
- Description The 16-bit AD7383-4 and 14-bit AD7384-4 are pin-compatible, quad, simultaneous sampling, high speed, successive approximation register (SAR), analog-to-digital converters (ADCs) operating from a 3.0 V to 3.3 V power supply with throughput rates up to 4 MSPS. The analog input type is a pseudo differential and is sampled and converted on the falling edge of CS. The AD7383-4/AD7384-4 have on-chip oversampling blocks to improve dynamic range and reduce noise at lower bandwidths. The oversampling boosts up to two bits of added resolution. A buffered internal 2.5 V reference is included. Alternatively, an external reference up to 3.3 V can be used. The conversion process and data acquisition use standard control inputs allowing easy interfacing to microprocessors or digital signal processors (DSPs). The conversion result can clock out simultaneously via 4-wire mode for faster throughput or via 1-wire serial mode when slower throughput is allowed. The devices are compatible with 1.8 V, 2.5 V, and 3.3 V interfaces using the separate logic supply. The AD7383-4/AD7384-4 are available in a 24-lead, 4 mm × 4 mm LFCSP and a temperature range of −40°C to +125°C. APPLICATIONS Motor control position feedback Motor control current sense Data acquisition systems Erbium-doped fiber amplifier (EDFA) applications Inphase and quadrature demodulation PRODUCT HIGHLIGHTS Quad simultaneous sampling and conversion. Pin-compatible product family. High 4 MSPS throughput rate. Space-saving 4 mm × 4 mm LFCSP. Integrated oversampling block to increase dynamic range, reduce noise, and reduce SCLK speed requirements. Pseudo differential analog inputs. Small sampling capacitor reduces amplifier drive burden.
